Estimated Glomerular Filtration Rate

Kidney Function marker

eGFR

Estimated Glomerular Filtration Rate

Category: Kidney Function
Unit: mL/min/1.73m2

Calculated estimate of kidney filtration rate. Below 60 suggests kidney disease.

PED Notes

Calculated from creatinine, so muscular athletes will show falsely low eGFR. An eGFR of 60-80 in a muscular individual is likely normal. Cystatin C-based eGFR is more accurate for athletes -- request this test to get a true picture of kidney function. If creatinine-based eGFR is low but Cystatin C is normal, kidney function is fine.

Supplements:

  • Astragalus -- 500-1000mg/day, kidney support

Lifestyle:

  • Stay well hydrated (3-4L/day)
  • Limit NSAID use
  • Request Cystatin C-based eGFR for accurate assessment
